[44net] BeagleBone Black unstable connection.

Hi, I'm moving my 44net connection from an OpenWRT device to a BeagleBone Black, because I've got a TNCblack to connect directly to a radio. However, in testing I'm finding the 44net connection doesn't stay up, max about 36hours before a reboot is required. Any ideas why this is, or how I could diagnose further. The device is always accessible via the local WiFi connection. Currently I've just got this tacked onto the end of my rc.local #Start 44net /usr/sbin/amprd -d -v 2> /var/log/amprd/amprd_err.log > /var/log/amprd/amprd_std.log & sleep 30 ip route add default via 169.228.34.84 dev ampr0 onlink table default ip rule add from 44.131.170.1 table default ip rule add from 44.131.170.1 to 44.131.170.0/30 table main sleep 10 ping -Iampr0 -c10 gw.ampr.org > /dev/null Device is on m1bkf.ampr.org - sometimes!
